TECHNICAL FIELD

The present application relates to mobile terminals, and more particularly, to form operation methods and apparatuses on a mobile terminal.

BACKGROUND

With the rapid development of communication technologies, most mobile phones use touch screens as input devices. Currently, methods for resolving issues of form operations on a mobile terminal in the industry may focus mainly on the following two aspects:

First, a form is submitted through an OK button after the form is filled out. The OK button may be located at the very bottom of the form. A user may need to slide the screen manually to the bottom of the form.

Second, a submit button may always be hovering around the bottom of the screen. The user may submit an order by directly clicking the hovering submit button. Although the button can sometimes be convenient to find, the size of the screen of the mobile terminal can make it difficult because the submit button may block part of the content of the form. As a result, the user may still need to scroll down the form.

The existing solutions may utilize clicking a button as the only means of submitting a form. However, operations on a mobile terminal must be as simple as possible and highly fault-tolerant due to limits of the size of the screen and the size of the palm. Therefore, the existing solutions may deteriorate user experience.

SUMMARY

The present application is intended to provide a method and apparatus for form operation on a mobile terminal. When a length of a form exceeds a screen display range of the mobile terminal, a user may do a specific operation through a hand gesture at any position on the screen.

To resolve the above technical issues, in one aspect, the present disclosure is directed to a method for form operation on a mobile terminal. Correspondence between hand gestures, hand-gesture comparison rules, and form operations may be preset. The method may include detecting an input hand gesture on a screen, and acquiring a trajectory of the input hand gesture. The method may also include matching the acquired trajectory of the input hand gesture with the hand gestures in the correspondence in accordance with the hand-gesture comparison rules. The method may further include triggering a corresponding form operation if the matching is successful.

In another aspect, the present disclosure is directed to an apparatus for form operation on a mobile terminal. Correspondence between hand gestures, hand-gesture comparison rules, and form operations may be preset. The apparatus may include a detection module configured to detect an input hand gesture on a screen, and acquire a trajectory of the input hand gesture. The apparatus may also include a matching module configured to match the acquired trajectory of the input hand gesture with the hand gestures in the correspondence in accordance with the hand-gesture comparison rules. The apparatus may further include a form-operation triggering module configured to trigger a corresponding form operation if the acquired trajectory of the input hand gesture matches the hand gestures in the correspondence successfully.

In a further aspect, the present disclosure is directed to a method for submitting a form on a mobile terminal. The method may include detecting an input hand gesture on a screen, and acquiring a trajectory of the input hand gesture. The method may also include matching the acquired trajectory of the input hand gesture with a preset hand gesture. The method may further include submitting the form if the matching is successful.

In yet another aspect, the present disclosure is directed to an apparatus for submitting a form on a mobile terminal. The apparatus may include a detection module configured to detect an input hand gesture on a screen, and acquire a trajectory of the input hand gesture. The apparatus may also include a matching module configured to match the acquired trajectory of the input hand gesture with a preset hand gesture. The apparatus may further include a form submission module configured to submit the form if the matching is successful.

The embodiments of the present application may have the following results and draw the following distinctions from the existing technologies. When the length of the form may exceed a screen display range of the mobile terminal, there may be no need to scroll down to the bottom to find an operation button. Besides, there may be no need to conduct a clear operation on a hovering operational button. The user may do a specific operation through a hand gesture at any position on the screen. As a result, an individual operational button may be not required while operating the form through hand gestures. The size-limited screen may be completely used for displaying the form content.

In one aspect, if complexity of an input customized hand gesture by the user does not meet a criterion, the embodiments of the present application may include prompting the user to re-input, which may prevent an accidental operation due to an overly simple hand gesture.

In another aspect, if the form is operable after filling in a password, the embodiments of the present application may include performing a password verification by using a pre-set hand-gesture password, and operating the form accordingly. The original two-step operations may be combined into one.

In a further aspect, the embodiments of the present application may ensure that the hand gesture set by the user is reproducible to avoid a low matching rate of the set hand gesture.

In another further aspect, a hand gesture in a hand-gesture triggering template having a high priority may be firstly matched with the acquired hand gesture, thus accelerating the matching speed.

DETAILED DESCRIPTION

In the following descriptions, many technical details are provided for readers to better understand the present application. However, those of ordinary skill in the art may understand that technical solutions claimed in the claims of the present application may still be implemented even without these technical details and various changes and modifications based on the following embodiments.

The embodiments of the present invention will be described below in detail with reference to the accompanying drawings to clarify the objectives, technical solutions, and advantages of the present application.

FIG. 1 is a schematic flow chart of an exemplary method for form operation on a mobile terminal, according to some embodiments of the present application.

In some embodiments, the method for form operation on a mobile terminal may include correspondence between hand gestures, hand-gesture comparison rules, and form operations preset therein. As shown in FIG. 1, the method may include the following steps.

Step 101: Detect an input hand gesture on a screen, and acquire a trajectory of the input hand gesture.

Step 102: Match the acquired trajectory of the input hand gesture with the hand gestures in the correspondence in accordance with the hand-gesture comparison rules.

Step 103: Trigger a corresponding form operation if the matching is successful.

In some embodiments, the form may be a form of an online shopping cart (e.g., Taobao online shopping cart) on the mobile terminal. In some embodiments, the form may be a form for adding vehicle information on an inquiry assistant application of regulation violation. FIG. 2 is an exemplary form of an online shopping cart on a mobile terminal, according to some embodiments of the present application. FIG. 3 is an exemplary form for adding vehicle information on an inquiry assistant application of regulation violation, according to some embodiments of the present application. These forms, including car model, query city, license plate number, engine number, vehicle identification number, and note, may be so long that a submit button may be blocked by a keyboard. But when the form may be submitted by using a hand-gesture operation, there may be no need to slide to the bottom of the form to find a “Checkout” or “Submit” button.

In some embodiments, the form operation may include submitting the form, deleting an entry in the form, or another relevant operations. A process of form operation may end here.

Accordingly, when the length of the form may exceed a screen display range of the mobile terminal, there may be no need to scroll down to the bottom to find an operation button. Besides, there may be no need to conduct a clear operation on a hovering operational button. The user may do a specific operation through a hand gesture at any position on the screen. As a result, through hand gestures, an individual operational button may not be required while operating the form. The size-limited screen may be completely used for displaying the form content.

In some embodiments, the method may further include prompting to re-input the hand gesture if the complexity of a customized hand gesture input by the user does not meet a criterion. It may avoid an accidental operation due to an overly simple hand gesture. When a hand gesture is added, the method may include prompting the user to input the hand gesture multiple times. Each hand gesture of the multiple hand gestures can be stored can correspond to a hand gesture associated with the correspondence. Having multiple hand gestures can ensure that the hand gesture set by the user is reproducible, and avoid a low matching rate of the hand gesture.

In some embodiments, before step 101, the method may further include prompting the user whether there is a need to add a hand gesture to the correspondence. If the user chooses to add the hand gesture, the method may also include displaying a hand-gesture setting page, detecting an input customized hand gesture on the screen, and setting a corresponding customized hand-gesture comparison rule and a corresponding customized form operation. The method may further include storing the detected customized hand gesture, the customized hand-gesture comparison rule, and the customized form operation in the correspondence.

In some embodiments, if the user chooses not to add a hand gesture, a default hand gesture may be used.

In some embodiments, a customized hand gesture may only be stored in the mobile terminal. When the user gets another mobile terminal, the customized hand gesture can be added again. Accordingly, it may bring a high level of security.

In some embodiments, detecting the input customized hand gesture on the screen may include determining whether complexity of the detected customized hand gesture meets a criterion. If the complexity of the detected customized hand gesture does not meet the criterion, the method may include detecting another input customized hand gesture. The criterion for the complexity of the customized hand gesture may include whether a number of inflections of a hand-gesture trajectory is within a preset inflection threshold.

The method may avoid an accidental operation due to an overly simple hand gesture by determining whether the complexity of the customized hand gesture meets the criterion.

In some embodiments, the method may include determining whether the complexity meets the criterion that may be set in accordance with another feature, not limited to the number of inflections.

In some embodiments, before storing the detected customized hand gesture, the customized hand-gesture comparison rule, and the customized form operation in the correspondence, the method may further include prompting the user to input the customized hand gesture multiple times. The method may also include detecting whether the multiple customized hand gestures match with each other. If there is a match, the method may include storing the detected customized hand gesture into the correspondence.

Only when the multiple customized hand gestures match with each other, the method may include storing the customized hand gesture into the correspondence. It may ensure that the hand gesture set by the user is reproducible, and avoid a low matching rate of the hand gesture.

In some embodiments, by means of pattern recognition technologies, step 102 of the method may include comparing an irregular pattern, drawn by the user on the screen through a hand gesture, with a locally stored pattern on the mobile terminal. If the comparison is successful, it may indicate that the method includes performing the operation of submitting the current form for one time.

FIG. 4 is a schematic flow chart of an exemplary method for form operation on a mobile terminal, according to some embodiments of the present application. The method may include the following steps.

In step 401, when the user may enter the form for the first time, the method may include prompting the user to add a hand gesture. If the user chooses to add, the method may also include displaying a hand-gesture setting page, and may enter step 402. If the user chooses not to set, the method may include adopting a default pattern, e.g., “√{square root over ( )},” and may enter step 406 to continue filling out the form.

In step 402, the method may include prompting the user to input an account password to verify the identity of the user.

In step 403, the method may include receiving input to add a customized hand gesture. The method may also include ensuring that an added customized hand gesture meets the required complexity of an irregular pattern in accordance with a specified recognition difficulty.

In step 404, the method may include ensuring the customized hand gesture. The method may include prompting the user to input the customized hand gesture multiple times for confirmation.

In step 405, the method may include adding the customized hand gesture. From a perspective of security, the method may include storing the customized hand gesture locally in the mobile terminal. When the user may have another mobile terminal, the user may need to add the customized hand gesture again.

In step 406, the method may include receiving information for filling out the form.

In step 407, the method may include receiving the customized hand gesture as input. When the user draws a previously set customized hand gesture at any position on the screen, the method may include submitting the form.

In some embodiments, when a customized hand gesture is added, the method may include ensuring that the added customized hand gesture meets the specified complexity to avoid a subsequent accidental operation due to an overly simple hand gesture. In some embodiments, the method may include prompting the user to input the customized hand gesture multiple times to ensure that the customized hand gesture is reproducible. In some embodiments, the method may include storing the successfully added customized hand gesture locally in the mobile terminal. It may bring a high level of security.

Some embodiments of the present application relate to a method for form operation on a mobile terminal. If the form is operable after filling in a password, the method may include performing a password verification by using a pre-set hand-gesture password, and operating the form accordingly. The original two-step operations may be combined into one. In some embodiments, a hand gesture in a hand-gesture triggering template having a high priority may be firstly matched with the acquired hand gesture, thus accelerating the matching speed.

After storing the detected customized hand gesture, the customized hand-gesture comparison rule, and the customized form operation in the correspondence, the method may further include querying the user whether there is a need to replace an input password by the stored customized hand gesture. If there is a need, the method may include displaying a password-setting page, and storing a set password in the correspondence. In the method, the step of triggering the corresponding form operation if the matching is successful may further include retrieving the stored password from the correspondence, and triggering a password verification operation.

Therefore, the method may include performing a password verification by using a pre-set hand-gesture password, and operating the form accordingly. The original two-step operations may be combined into one.

In some embodiments, the method may not include setting the password as described above.

In some embodiments, the step 102 of the method may include extracting a feature value of the input hand gesture, and comparing the feature value with a feature value of a hand-gesture comparison rule in the correspondence. The step 102 of the method may also include calculating a number of inflections of the input hand gesture, and comparing the calculated number of inflections with an inflection threshold of the hand-gesture comparison rule in the correspondence.

In some embodiments, the method may include matching sequentially in accordance with a certain manner. In some embodiments, the correspondence in the method may include at least one set of a hand gesture, a hand-gesture comparison rule, and a corresponding form operation. Each set may constitute a hand-gesture trigger template. In step 102 of the method, matching the acquired trajectory of the input hand gesture with the hand gestures in the correspondence may include matching sequentially in accordance with priorities of hand gesture trigger templates. In other words, the step 102 of the method may include matching the acquired trajectory of the input hand gesture with a hand gesture of a hand-gesture trigger template having a high priority. The priorities of hand-gesture triggering templates may be sorted in accordance with historically cumulative operational numbers of hand gestures in the templates.

In some embodiments, the method may include sorting the matching sequence of the hand-gesture triggering templates in accordance with other manners.

Some embodiments of the present application relate to a method for submitting a form on a mobile terminal. FIG. 5 is a schematic flow chart of an exemplary method for submitting a form on a mobile terminal, according to some embodiments of the present application.

As shown in FIG. 5, the method may include the following steps.

Step 501: Detect an input hand gesture on a screen, and acquire a trajectory of the input hand gesture.

Step 502: Match the acquired trajectory of the input hand gesture with a preset hand gesture.

Step 503: Submit the form if the matching is successful.

In some embodiments, before step 501, the method may further include prompting a user whether there is a need to add a preset hand gesture. If the user chooses to add a present hand gesture, the method may include displaying a hand-gesture setting page, and detecting an input customized hand gesture on the screen. The method may also include storing the detected customized hand gesture to be the preset hand gesture.

In some embodiments, after storing the detected customized hand gesture to be the preset hand gesture, the method may further include querying the user whether there is a need to replace an input password by the stored customized hand gesture. If there is a need, the method may also include displaying a password-setting page, and storing a set password. In the method, the step of submitting the form if the matching is successful may further include retrieving the stored password, and triggering a password verification operation.

FIGS. 6-8 are snapshots of major pages in an exemplary method for form operation on a mobile terminal, according to some embodiments of the present application. As shown in FIG. 6, when the user enters the form for the first time, the method may include prompting the user that the form may be submitted through a hand gesture. The method may also include prompting the user that a customized hand gesture may be used to submit the form. As shown in FIG. 7, after the customized hand gesture is set successfully, the method may include querying the user whether there is a need to replace an input password at this moment. As shown in FIG. 8, the user may submit the form by operating the previously set hand gesture at any position on the screen.

The embodiments of the present application may provide the following technical results:

1. It may only be necessary to add a hand gesture for the first time or event. In some embodiments where a default hand gesture is used, it may be unnecessary to add any hand gesture. For subsequent form submissions, the user may only need to operate the added hand gesture or the default one at any position on the screen to submit the form.

2. When the length of the form may exceed the screen display range, there may not be a need to scroll down to the bottom to find a submit button. The user may submit the form through a specific hand gesture at any position on the screen.

3. If a form may be submitted only after filling in a password, the user may pass the password verification process through a previously set hand gesture password and submit the form at the same time. The original two-step operations are combined into one.

All method embodiments of the present application may be implemented by means of software, hardware, firmware, or the like. No matter these method embodiments are implemented by means of software, hardware, or firmware, their instruction codes may be stored in any type of computer accessible memory, such as permanent or modifiable, volatile or non-volatile, solid-state or non-solid-state, and fixed or replaceable medium.
